`Arrow, McGrath and Berdahl's Small Groups as Complex Systems will change the way you think about research, and even the way you think about science.... The book is excellent, one of those very rare works that will have substantial impact on the field. I would use the book without hesitation in any advanced graduate seminar dealing with groups' - Donelson R Forsyth, Virginia Commonwealth University

This new general theory of small groups as complex systems draws on general systems theory, dynamical systems theory, and complexity and chaos theory.

The authors view groups as adaptive, dynamic systems that are driven by interactions among group members and by transactions between the group and its embedding contexts, as well as by external pressures.

By virtue of the empirical material integrated within this elegant analysis, the authors offer a more complete understanding of the nature of group behaviour and the factors which shape it.
